Worked on the archlinuxcn/repo project to enhance dependency stability and expand hardware compatibility. Addressed a critical issue by upgrading the tree-sitter-git package to ensure compatibility with tree-sitter 0.26, and adjusted versioning through an epoch bump for accurate package tracking. Introduced AArch64 support, enabling builds and deployments on ARM64 hardware, which broadens the repository’s usability across architectures. Focused on maintaining repository stability with minimal surface changes, validating all updates through continuous integration pipelines. Utilized Shell scripting and expertise in build systems and package management to deliver targeted improvements that reduce maintenance risk for downstream users and improve build reliability.
